What is the treatment if responder hand is a natural 2d response? e.g.
1S--1NT--2C!(Gazzilli)--?

Good hand for reverse Gazzilli, where 1♠-1NT-2♣ shows 16+ or 11-15 with 6+ spades. In that case, you can bid 2♠.

Playing standard Gazzilli, this may be a 2NT rebid, depending how you defined that, else you'll have to bid 3♦.

Assuming

1♠-1N; 2♣ = "11-15", 4+ C / "16+", any,

I've always thought standard rebids by Responder are something like

2♦ = "8+", any [GF opposite the strong option]
2♥+ = "5-7", nat.
Specifically:
2♥ = "5-7", 5+ H
2♠ = "5-7", 2S4-H [also with "4-6", 3 S if you play 1♠-2♠ as constructive]
2N = "5-7", 5+D4+C or 4H5+D, usually 1- S [=> 3♣ = to play opposite 4+ C (=> P = 4+ C; 3♦ = 4H3-C)]
3♣ = "5-7", 4-H4-D5+C, usually 1- S
3♦ = "5-7", 3-H6+D4-C, usually 1- S

Notice that hands with 5-7, 1444 are unbiddable on this interpretation.

3♦. But I prefer pass to 1NT. If I am sub-minimum I like a get-out in partner's major.

I was playing 2N=minors, so you'd squeeze 1444 there. Also, everything other than 2♠ was showing 0-1 spades. It's possibly better to keep the 2H response a bit vaguer but OK. This was standard Gazzilli in Iceland, called "Hexan", I think from originally Sweden, but not sure how widespread there, or in N Europe or anywhere else in Europe.

I feel responder should give better definition of his heart length when he has less than 8 points after 1♠-1NT-2♣.

So 2NT = 4 hearts precisely and at most 1 spade, less than 8 HCP. Accordingly the bid shows 8-9 cards in the minors.
3♣ shows 4 or more clubs, no 4 cards in hearts and 9 or more cards in the minors.
3♦ shows 6 or more diamonds, no 4 cards in hearts.
After 3m opener will bid 3♥ only with 5.

This provides slightly less definition on the minors, but better definition of the hearts.
Over 2NT opener with 4 or more hearts has excellent information to decide whether to play 3♥ or 4♥ or in exceptional cases even 6♥.
Minor suit games are a long way off if responder has less than 8 HCP.

This is pretty cool, thanks. Makes much more sense!

Back to the original question rather than people using customized Gazilli versions:

1. It is usual to play 2NT as weak with both minors and a diamond preference, and 3♦ as simply weak with a long suit. The given hand would bid 3♦.
2. With doubleton spade it is often better to bid 2♠ rather than try to introduce your diamonds, since you will have to go to the three-level to do so.

I play 1♠-1NT-2♣ as 11-16 ♠ & ♥ or 17+
So 2♥ is preference on any 4+card suit or 13(45)
That way 2NT is 5-5 minors & 3m is 6-cards
You can play 3♥⁺ as showing 6-card heart suit and a positive

One of the things I thought I had invented, too. Then I read this:
